BARN-DOOR HANGER.

Specification of Letters Patent.

Patented Feb. 15, 1910.

To all whom it may concern:

Be it known that I, WILLIAM F. James, a citizen of the United States, residing in Ottawa, in the county of Lasalle and State of Illinois, have invented a newand useful Improvement in Barn-Door Hangers, of which the following is a specification.

This invention relates to hangers for sliding doors and has been devised more espe-.

clally for use with the sliding doors of barns. My endeavor in it has been to provide such doors with means permitting easy adjustment of the same both vertically and laterally and with rollers which will render their movements very easy, and which will adapt them to use with tubular tracks inclosing the rollers.

The nature of my improvements will be understood from the description which I give below and from the accompanying drawings, in which .latter Figure 1 is a partial front elevation of a door provided with my invention; Fig. 2 is an edge view of the same partly in section; Fig. 3 is a front elevation of one of the rolling supports; and Fig. 4 is a section on the line 41 of Fig. 3.

In said drawing 5 represents the door and 6 is the wall of the barn or other structure to which the door is applied. 7 is a tubular track supporting the door and attached to the barn or other structure at proper points by brackets 9. The tubular track and the brackets are slotted longitudinally along the bottom as shown at 8 giving passage room for the connections between the rolling supports and the door.

The rolling supports which I have adopted consist of freely rotating rings 10 which are supported upon hubs 11 at each end of a casting 12. The rings are carried each by a series of balls 13 moving around a runway formed by the hubs 11 and the confining plates 14 at the sides of the casting. The casting 12 has two depending arms 15 integral with it and each of these arms has an opening 16 adapted to receive the ends of a pivot 17 which passes through a sleeve 18 and confined in said arms by the head 17* at one end of the pivot and cotter pin 1'7 at the other end. Depending from the sleeve 18 is a nut 19 integral with the sleeve and in this nut is threaded a screw 20 supported at its ends in the upstanding arms 21 and 22 of the hanger plate 23 through which the mg hubs at each side,

door is raised and lowered as required, and also adjusted to and from the building as will be understood from the following description. This piece 23 has a depending arm 24 on the lower end of which a screw 25 is formed. This arm is bent outward from the door as plainly seen at Fig. 2 so that room may be obtained without cutting away the door for the adjusting nut 26. This screw is partly covered by a housing 27 and to this housing are attached two horizontal plates 28 and 29 having vertical openings through which the screw 25 passes, and the open space between said plates receives the nut 26 and confines the same. The housing is rigidly attached to the door by bolts 30 and 31 and consequently when the nut 26 is turned upward so as to bear against the plate 28 of the housing the door will necessarily be raised. The door is adjusted to and from the barn by means of the screw 20 as will be understood and it is free to swing on the pivot 17.

In the construction described very considerable pressure upon the rings is caused partly by the weight of the door and partly by the transverse curved form of the track. This pressure forces the bottoms of the rings toward each other so that they tend to bind against the sides of the casting. To prevent this I place two anti-friction balls 32 in a cross passage 33 formed in the casting 12 between the runway and somewhat below them, the balls 32 being in contact with each other and adapted by their location to press outward upon the rings and thus relieve the friction upon the latter.

I claim 1. In a door hanger, a roller support comprising in its construction a central casting 12 having hubs at each side, independent rings 10 mounted upon anti-friction balls revolving around said hubs, and side plates for confining said balls and rings.

2. In a door hanger, a roller support comprising in its construction a central casting 12 having hubs at each side, and also having integral depending arms, supporting a pivot on which the door may swing, rings 10 mounted on anti-friction balls revolving around said hubs and side plates confining said balls and rings.

3. In a door hanger, a roller support comprising in its construction, a casting l2 hava freely revolving ring upon each hub, anti-friction loalls supporting tion with a tubular track and horizontally 10 sald mugs, and horlzontally acting spacing acting antifriction devicesbet-Ween the rings balls between the rings. tending to relieve the friction between the In a door hanger, a roller support comrings and the castlng.
